The invention relates to a device for suppressing positional deviation opposite to movement resulting from operating clearance in a reduction gear including two gear trains. The invention relates to a reduction gear comprising a fixed inner ring gear (3) which is concentric with an input shaft (7) and which is provided with an eccentric portion (7E) driving, during the rotation thereof, an orbital wheel (4) consisting of two secured outer gears, one gear (4Z) meshing with the inner ring gear (3) and the other gear (4X) meshing with the inner ring gear (5Y) of the output shaft (5). Two elastic systems (18) and (20) constantly suppress the operating clearance by locking the teeth for driving the outer gears (4Z) and (4X) of the orbital wheel using the inner ring gears (10) and (9). The device according to the invention is to be used particularly in robotics. |
